PATENT COMBINATION ROLLER PRINTING ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 643,154, dated February 13, 1900.

Application filed January 26, 1899. Serial No. 703,466. (No model.)

To all whom, it may concern:

Be it known that I, WILLIAM M. PEARSE, J12, a citizen of the United States, residing at Zanesville, in the county of Muskingum and State of Ohio, have invented a new and useful Automatic Combination Roller Printing- Machine, of which the following is a specification.

My invention relates to roller printing-machines chiefly designed for use by retail merchants and dealers for printing advertisements on wrapping-paper and which are adapted to be connected with the frame of a paper-roll and to be automatically operated by the unwinding of the paper from the roll.

The object of the invention is to provide an improved construction of such machines whereby the printing-roller can be returned automatically to normal position after making an impression or which can rotate in the same direction to bring it into operative position, as may be desired.

The invention consists in the novel construction and combination of parts hereinafter fully described and claimed.

In the accompanying drawings, Figure l is a perspective view of a printing-machine constructed in accordance With my invention attached to a paper-roll frame. Fig. 2 is a similar view showing the means for connecting the printing-machine with the frame. Fig. 3 is a similar view of the printing-machine detached from the frame. Fig. 4 is a detail end elevation of one end of the printing-roll. Fig. 5 is a detail longitudinal section of one end of the printing-roll and end plate of its frame. Fig. 6 is an elevation looking from the inner side of the spring-actuated disk.

In the said drawings the reference-numeral 1 designates the frame of the printing-machine,comprising the bottom bar 2, top bars 3,

and end plates 4. Each of these end plates is formed with a slot 5, in which the journal 6 of a printing-roll 7 has its bearings, and which journal is held in place by a spring 8, secured to a projection of said end plate. This printing-roll is preferably made of rubber or other elastic material and has thereon characters in relief of any description desired. Near the ends said rollers are formed or pro vided with peripheralbearings, 9 of rubber, which are about the same distance from the periphery of the roll as the characters or type which print the impressions. Formed in each of the said end plates 4 are two slots 10 and 11, in which the journals 12 of inking-rollers 13 and 14 have their bearin gs. These rollers are connected with each other by a coiled spring 15 and are also connected with a pin or screw 16, secured to the end plates 4. Said rollers contact with each other, and roller 14 contacts with the printing-roll, the roller 13 being the roller which first receives the ink.

Formed in one end of the printing-roll is a cylindrical recess 17, in which is located a disk 18, with a circular recess in the inner side with which engages a pin 19, secured to the said printing-roll. The ends of this groove are separated by a partition 20, while at one end of said ends is an intersecting hole 21 for ascertaining the position of the said pin. Secured to said disk is one end of a convolute spring 23, the other end of which is connected with one of the journals of the printing-roll. Secured to or formed with said disk are two lugs 24, between which is adapted to engage a set-screw 25, which projects through one of the end plates 4. The said frame 1 is provided with an upwardly-extending bar 26, formed intermediate its ends with a hole 27 and near its upper end with a slot or opening 28. I

The numeral 29 designates a paper-roll frame of any ordinary or suitable description provided with a paper-roll 30. Connected with the upper bar 31 of said frame is a clamp comprising a horizontal portion 32, with an up wardly-extending jaw 34 and 35 at the ends. One of these jaws 34 is formed with a sharp ened rib 36, while the other jaw 35 is provided with a set-screW-37, passing through a screw-threaded opening therein. Said clamp is provided with a nextension 38, having a downwardly-extending lug 38 at the outer end. Connected with this lug are two coiled springs 39, which in turn are connected with a chain 40, which is passed through the hole 27 in the bar 26 and is held in engagement therewith by a pin 44 on the end of the chain. The inner jaw 34 of said clamp is provided with an arm 41, having a disk 42 at the end,

and is formed with two opposite shoulders 43. This disk passes through the opening near the upper end of bar 26 and the shoulders limit its movement.

The frame of the printing-machine is provided with a cover-plate &5, which is held in place by spring-catches 46, which engage with the topand bottom bars of said frame.

The operation is as follows: The clamp is secured to the top bar of the paper-roll frame and the disk 42 passed through the opening in bar 26 and the chain passed through the hole in said bar. The tension of the springs 39 is regulated by passing more or less of the links of thechain 40 through said hole and engaging the pin 44 with one of said links. The printing roll will now be pressed against the paper coil. In normal position the pin 19 rests against the partition 20, and if the said roll is to be used as an oscillating rollthat is to say, if it is to be returned to normal position by the spring 23 after having made an impression-the set-screw 25 is operated so that the inner end thereof will engage with the lugs 24, so as to hold the disk 18 stationary. Now in pulling a length of paper from the roll the friction between the bearings at the end of the latter and of the paper will cause the roll to be rotated and an impression printed on the paper. This will wind up the spring. \Vhen the paper has been torn off, the roll is moved slightly away from the paper-roll by the operator. when the tension of the spring will return it to normal position.

By disengaging the pins 23 from the lugs 24 the disk 18 will turn with the printing-roll and the spring will not be wound up, so that the said roll and disk will always move in one direction.

Having thus fully described my invention, what I claim is- 1. In a printing-machine of the character I described, the combination with the frame and the spring-actuated inking rollers, of the printing-roll journaled in said frame, having a recess in one end, the disk having a circular groove in its inner face, the partition separating the ends of the same, the pin engaging therewith, the oonvolute spring secured to said disk and the journals of the printingroll, the lugs on said disk and the set-screw passing through the said frame, and engaging with said lugs, substantially as described.

2; The combination with a printing-niachine, and the bar thereof formed with a hole and'a slot or opening, of the paper-roll frame, the clamp having jaws and a set-screw, and the arm provided with a disk passingthrough the opening in said bar and formed with shoulders, a coiled spring connected with said clamp, the chain connected therewith passing through the hole in said bar and the pin on the end of said chain, substantially as described.

3. The combination With a printing-machine provided with a bar having an opening near one end and a hole intermediate the ends, of the paper-roll frame, a clamp secured thereto having jaws, one of which is provided with a rib, and the other with a setscrew, said clamp carrying an arm having a disk and shoulders, also an extension provided with a lug, the spring connected therewith, the ehain, and the pin on the free end of said chain, substantially as described.
